I've created a CPListTemplate with dynamic list entries from an API. All entries are different music channels. In my ForEach for generating all list entries, I've set the .isPlaying property to true and also the playingIndicatorLocation to .trailing. If I play a channel, the isPlaying indicator is animated on every list entries. I've set different metadata in the MPNowPlayingInfoCenter and this is correct inside the CPNowPlayingTemplate. Do I need to set some identifier somewhere, so my list template knows which channel is currently playing? If so where can I set this?

I'm trying to match the id of the song currently playing with the id of the song I added to the queue, but they never match. musicPlayer.queue = [mySongVar] print(mySongVar) This will print out: Song(id: "i.eoqMkIkPJ9Ea", title: "À peu près", artistName: "Pomme") then I tell the musicPlayer to play what's in the queue and print: print(musicPlayer.queue.currentEntry!.item!.description) And I´ll get this: MusicPlayer.Queue.Entry.Item.song(Song(id: "1440887303", title: "À peu près", artistName: "Pomme")) I don't understand why the Song.id for the Item for the queue's current entry is a a certain string, but the if for my original Song object I sent to the queue is something else entirely. I'm not sure if I'm going about this the wrong way. I'd really appreciate some help/guidance! Thanks" By the way: let musicPlayer = ApplicationMusicPlayer.shared

I'm integrating Apple Music on my ios app, and I want to change the volume programmatically. I'm using: let player = MPMusicPlayerController.applicationQueuePlayer player. But I found that this player doesn't have an API for changing volume. Any solutions, please?

Version： 14.x Setting videoGravity of AVSampleBufferDisplayLayer does not work, however, when I change bounds of this layer, it worked, is this a bug or feature? but in iOS 15, this propery worked well.

when i played a fairplay streaming by avplayer,calling copyPixelBufferForItemTime on AVPlayerItemVideoOutput the pixelbuffer returns NULL.is there any way to get the pixel buffer from a stream that is protected using FairPlay on iOS or apple's APIs in order to display FairPlay stream on an OpenGL texture in 3D space?

Hi, I'm trying set playbackState like swift MPNowPlayingInfoCenter.default().playbackState = .playing But I receive an error in console. [NowPlaying] [MRNowPlaying] Ignoring setPlaybackState because application does not contain entitlement com.apple.mediaremote.set-playback-state for platform I tried to add it to applications *.entitlements file: xml     keycom.apple.mediaremote.set-playback-state/key     true/ But after that I cannot even build my application due to signing error: Provisioning profile "iOS Team Provisioning Profile: app.name" doesn't include the com.apple.mediaremote.set-playback-state entitlement. I use a free development certificate if it is important. Xcode version is 12.4. Did anyone face with same issue? What do I wrong? What should I do to solve an issue? Thanks for any help!

Hi all, I have enabled the ChromeCast icon via Google Cast SDK framework in my app. I am able to cast to my TV, that works fine. But, I cannot cast any media. It says "No media selected" although I am opening a video file and play it. I have an app that is connected to my website so I use UIWebKit and WebView to display my content. On my site I have lots of videos that I would like to be able to cast via ChromeCast, just like Netflix and other streaming video apps. Does anyone know if this is possible and if so, what is needed in the code to make that possible? Thank you very much in advance!

Hi! I'm having a problem that I cannot seem to figure out. I have not made any changes to my app, yet this suddenly started happening. I think it started happening after I upgraded my phone to iOS 16.3.1, but I am not entirely sure. Pseudocode: // (1) initialise player let player = MPMusicPlayerController.applicationMusicPlayer // (2) ..later, a button is pressed and we call play() player.play(myAlbumId) // (3) a background timer runs, which will ensure we are playing for 30 seconds, and pausing for 60 seconds (this is a workout app): self.timer = Timer(timeInterval: 1.0, target: self, selector: #selector(togglePauseIfNeeded), userInfo: nil, repeats: true) RunLoop.current.add(self.timer!, forMode: .common) // (4) Now, the problem occurs when the timer triggers play, the second time we are playing music (ie, it works the initial time, but in that case, play was triggered by a button press (step 2)). // So when the timer now calls player.play(), we see this error: "[SDKPlayback] applicationController: xpc service connection interrupted" player.play() Interestingly, if I manually hit play just a few seconds before the timer would have called "play" (at step 4), it works fine. Any thoughts or help on this would be highly appreciated! <3

Hello i was setup an Podcast rss under the following url: https://www.eybwallwitz.de/feeds/podcasts/ But i dont get it up running. When i validate the Feed with https://podba.se/ it says: everything is ok: https://podba.se/validate/?url=https://www.eybwallwitz.de/feeds/podcasts But when i use https://www.castfeedvalidator.com/validate.php?url=https://www.eybwallwitz.de/feeds/podcasts i get the Message: FATAL: This server does not support HTTP head requests. Head request support required for Apple Podcasts. Did not finish media tests. I really dont get the problem. I use a nginx 1.18 webserver. Cause i didnt found the problem i explicit allowed HEAD, GET, POST, Options on Feed URL I adjustet mp3 urls with content-disposition: inline; filename="$filename" But nothing works. I tryed to load the feed into my podcast app but the feed from url didnt work, so validator 2 looks like to be right, that there is a problem. i used curl --head to verify check and compare between an old feed an the new one old: https://2020.eybwallwitz.de/de/publikationen/podcast/feed/ new: https://www.eybwallwitz.de/feeds/podcasts/ i expect the problem somewhere in nginx. so if u need more infos, please give me a sign. also when u have any idea what i can do/test to get this problem away. currently i dont have any idea left. thx peter

I am using RealitKit SDK to insert audio into the AR program. According to the description on the official website, I need to use the class AudioFileResource to load audio, and then the Entity object calls the prepareAudio() method to get an AudioPlaybackController, which is used to play audio, but there is no sound. Has anyone ever encountered this situation?

When playing music or a podcast in the Spotify application (as well as using car play), an audio notification may occur from the Waze application, after the notification, playback in the Spotify application usually continues automatically. Well, the new update does not work properly to automatically resume listening, you need to press play again in the Spotify app. Please fix it, it's very annoying.

In iOS 16.4 Beta 1, the indexOfNowPlayingItem returns unexpected/incorrect value. In prior versions of iOS, the value returned was expected. I also plan on submitting a detailed bug report on Feedback Assistant once I have more details.

I have to make sure that I have fully loaded the videos before playing them. I went through the Apple documentation but couldn't find how to do it. I tried AVAssetDownloadTask but I don't want to keep the files. I want them to be deleted after the app is closed. Is there a recommended method for this? I need to make sure the videos are fully downloaded and ready to play. So AVPlayer's default behavior doesn't work for me

Hello everyone, Apple CarPlay is implemented in one of my applications by using MediaPlayer Framework. It is working properly if iPhone is locked, the App is in the background, or in an Active state. But I want to play audio from CarPlay even if the App is in a terminated state similar to Spotify app does. In case of application is not opened in the phone, on CarPlay display selecting the station does not play the song. You can see in the below videos for both cases: [https://algoworks-my.sharepoint.com/:v:/p/ankit_singh/EQ3HzSKEl-pGpMIK0vh7HIkBtWg50-vco3aTyxOZevmuTA?e=2pmmWB) [https://algoworks-my.sharepoint.com/:v:/p/ankit_singh/EeI8qai1iftKvwo9nogCJREBFQXCf3qf8d-qwIt-25CB7g?e=bkYqAH) I tried many things but not able to achieve this. So help me with this and share some code to review. Thanks.

I am working on an app that makes a custom alarm so I am using long music from outsourced platforms like Spotify, everything is done but the current issue is when I try to play the music when the phone is locked it doesn't work on a physical device but works on the simulator!, what I am doing is schedule a local notification to turn on the screen at this time then play the music from a scheduled timer. Here is the snippet of the code responsible for this. let timer = Timer(timeInterval: time.timeIntervalSinceNow, repeats: false) { timer in // Doing the task here! playAlarm() } RunLoop.current.add(timer, forMode: .common) Note: To run this task when the phone is locked I am sending a local notification at this time to turn on the screen to make it possible to run this task. Please let me know if this is possible as I see some apps doing this

Hello, I am working on a Mac app and I would like to be able to get notifications (NotificationCenter.default.addObserver.add... MPMusicPlayerControllerPlaybackStateDidChange) when media starts to play in other apps. Is this possible on Mac? Thanks in advance!

I'm currently developing an app that can reproduce audio and video from the web (my own server) using SwiftUI targeting iOS15 and testing on a iPhone XS Pro Max running iOS16.2 (real device) Both the video and audio play just fine but I get this (image in the end of the post) in as the media controls. The current time and duration are correct and updated (without me calling to update them) but I'm unable to actually update the title, artist, album and artwork My first thought was to update the NowPlaying and after a lengthy search I'm yet to find a solution that works I created a small class to update the NowPlaying info import Foundation import UIKit import MediaPlayer public class MediaController {     var nowPlayingInfo = [String: Any]()     static let shared = MediaController()     private init() { }     func setupNotificationView(title: String?, album: String?, artist: String?, thumbnailUrl: String) {         nowPlayingInfo = [String : Any]()         nowPlayingInfo[MPMediaItemPropertyTitle] = title         nowPlayingInfo[MPMediaItemPropertyAlbumTitle] = album         nowPlayingInfo[MPMediaItemPropertyArtist] = artist MPNowPlayingInfoCenter.default().nowPlayingInfo = nowPlayingInfo     } } The NowPlaying still doesn't update This is the call sequence when I press play let avAsset = AVURLAsset(url: URL(string: "https://domain.com/video.mp4") let avItem = AVPlayerItem(asset: avAsset) player.replaceCurrentItem(with: avItem) do { try AVAudioSession.sharedInstance().setActive(true); } catch { print(error) } player.play() MediaController.shared.setupNotificationView(title: "A Title", album: "A Album", artist: "A Artist", thumbnailUrl: "") Although the app is being developed using SwiftUI I'm using the UIViewControllerRepresentable to display a the video using AVPlayerViewController since the current one misses the PiP and under makeUIViewController I have the following code let controller = AVPlayerViewController() controller.player = player controller.allowsPictureInPicturePlayback = true controller.entersFullScreenWhenPlaybackBegins = true controller.delegate = context.coordinator and on the app launch I have the following let audioSession = AVAudioSession.sharedInstance() do { try audioSession.setCategory(AVAudioSession.Category.playback) } catch { print("Setting category to AVAudioSessionCategoryPlayback failed.") } And yes I have the background mode capability enabled for "Audio, AirPlay and Picture in Picture" I'm at a lost here and hope someone can help.
